Abstract
A tissue displacing and fastening device is provided for manipulating and fastening tissue together. The device includes a tissue displacing elements, which displaces tissue. A fold is formed from the displaced tissue and the tissue is fastened together to secure the fold.
Claims21
1-7. (canceled)
A tissue shaping device, comprising:
- a distal end configured to be inserted into a stomach of a patient, the distal end comprising:
- a shaft;
- an outer wall disposed around the shaft;
- a recess disposed between the shaft and the outer wall;
- a first displacing element disposed within the recess and configured to extend from and retract to the recess;
- an engaging element disposed at a longitudinal end of the displacing element;
- a fastener disposed within the recess, the fastener configured to fasten folds of reshaped tissue;
- a control handle proximally connected to the distal end, the control handle comprising:
- a first actuator configured to extend and retract the first displacing element from within the recess;
- a second actuator configured to cause the engaging element to engage the tissue.

A device for forming a fold of tissue at the intersection between the esophagus and the stomach, comprising:
- a distal end configured to be inserted into the stomach of a patient, the distal end comprising:
- a shaft;
- an outer wall disposed around the shaft;
- a recess disposed between the shaft and the outer wall;
- a displacing element disposed within the recess and configured to extend from and retract to the recess and configured to reshape the stomach tissue;
- a reinforcing element mounted on the shaft, the reinforcing element comprising:
- a first side configured to attach to an anterior side of the reshaped stomach tissue;
- and
- a second side configured to attach to a posterior side of reshaped stomach tissue;
- a fastener disposed within the recess, the fastener configured to fasten the reinforcing element to the reshaped stomach;
- and
- a control interface proximally connected to the distal end, the control interface comprising:
- a first actuator configured to deploy the reinforcing element from a stored position to a deployed position;
- and
- a second actuator configured to move the fastener between a stored position and a deployed position and thereby fasten the reinforcing element to the reshaped stomach tissue.

A device for forming a fold of tissue at the intersection between the esophagus and the stomach, comprising:
- a distal end configured to be inserted into the stomach of a patient, the distal end comprising:
- a shaft;
- an outer wall disposed around the shaft;
- a recess disposed between the shaft and the outer wall;
- and
- a displacing element disposed within the recess and configured to extend from and retract to the recess and configured to reshape the stomach tissue;
- a slot configured to allow radial movement of the displacing element relative to the shaft;
- and
- a control interface proximally connected to the distal end, the control interface comprising:
- a first actuator configured to initiate radial movement of the displacement element relative to the shaft.
